To allwbom 'it may concern:

of this class of simple and cheap construction the parts of which are light and so organized as to render the machine capable of being run at higher speeds than machines as heretofore constructed, 1vvhile proy brai lng machine embodying ducing the bestresults in braiding.

@ne of the rinci al features of the machine. that distinguis es it from other braiding machines heretofore used is the employment of simple pattern-changing mechanism A:for producing at will braids having their threads interlaced in various ways, and this pattern-changing mechanism is so constructed and operated ns to produce various changesv in the mode of interlacing the threads and hence in the braid produced, b v mere adjustment of simple and light. threadweaving devices capable of effective operation at high speeds.

Other important features of the invention will be hereinafter described and claimed and are illustrated in the accompanying drawings` in which- Fi ure 1 is a plan, partly in section, of a my present in vention; Fig. 2 is a central vertical section of the same. the section being taken in the line 2 2, Fig. 1; Fig. 3 is an enlarged plan of a portion of the machine shown in Fig. 1, and illustrates in greater detail than 1u said figure various thread-supplying and pattern-controlling devices; Iig. 4 is an enlarged sectional detail, the section being taken in the line-1 4, Fig. 1, illustrating a pair of inner and outer bobbin-holders 'zoether with a pattern-controlling device for eterminin the manner in which the inner and outer t reads fed from the hobbins shall be interlaced; Fig. 5 is a substantially similar sectional detail illustrating the manner in which the outer threads are raised above i the inner threads h'yr means of a switchating parts and illustrates the manner in which the -outer thread is raised above its..

Fig. 11 is a pergspective of a removable sec` tion'of one of the carriers for the bobbins.

Similar characters designate like parts in all the figures of the drawings.

Referring first to Figsrl and 2, many of the parts o the machine are preferably substantially the same as in braidin machines heretofore constructed, and for t e pur ose of illustration these parts are so shown. or example, the machine shown in these views is illustrated as having a bed or base' 2 from which rise's s hollow xed post 3 having an external jonrnal surface on which turns a lon sleeve 4. At the .lower end thereof this s eeve 4 has secured thereto a large bevelear 5 by means of which the sleeve 1s rotate and at a point a considerable distance above said bevel-gear said sleeve has an annular support 6 for' another large bevel-gear 7 which is fixed to the hub rtion 8 of the rotary carrier 9 journale on the upper portion of the sleeve 4. The rotary cai'rier or table 9 in turn constitutes a support for the hub portion 10 1f-another rotary carrier or table 11, which is fixed to the upper end of the sleeve 4. The bearin surfaces of the various parts just descrb are separated in the wel known manner by antifriction or fiber washers. such as are illustrated at I12, 13 und 14. .The two carriers or tables 9 and 11 are intended to be rotated in opposite directions by means of the gears 5 and 7, these being driven in the usual hihnner by a bevel-gear 13 .secured to the end of a main driving-shaft 1G mounted in suitable bearingssueh as 1T and 1H. ris ing from the base of the machine, said shaft having at its end the usual fast-and-loose pulleys 19 and Q0. ,lt the outer end ol'A the tubular base 3 is placed a stop 2l for limiting upward movement of the carrier 1l.

` In connection with the devices just described there is also shown the usual overhanging arm 22 rising from one side of the base of the machine and extending at itsv free end to the braiding point., it having at such a point the usual gatherer 22. in abnement with the axis ot the base 3 through which the core to be braided is passed. This core is indicated at Q4, and may be fed upward in the usual manner by pull-eti device (not shown).

The two carriers -9 and l1 support, as is usual, two sets of thread-supplyin nr devices, which are generally in the form o t' bobbins mounted on bobbin-holders, one set being located outside the other and se positioned that the threads of one se*J may be readily shifted to one side or the other of the threads of the other set and interlaced therewith as they pass the threads of such other set.

In Fig. 1, eight sets of bobbin-holders are shown on each carrier and each holder carries a bobbin. The bobbin-holders of the outer set are designated respectively by 25 and those, of the inner set by 26. Corres ondingly the bobbins of the outer set. are

esignated by 27 and those of the inner set .by 28. As in other machines of 'this type, the two sets of bobbin-holders and the bobbins carried thereby arc intended to move orbitally on their carriers in opposite directions, it being obvious that one of the carriers 9 and 11 is rotated in one direction by fits bevel-gear 'i while thc other is rotated in the opposite direction by the bevel-gear 5, both of these bevebgears being rotated in time with each other but in opposite direc tions by the driving bevel-gear 15.

An important feature ot' the two sets of thread-supplying devices is that both of them are of simple construction, the main element of each bobbin-holder being merely a spindle or pin fixed at its outer end to its carrier and free at its inner end to permit its bobbin to be quickly placed in position or removed. This reduces considerably the wei ht of the parts to be rotated and also faci itates the insertion of filled bobbins and force during rotation of their carriers, while at the same time permitting the threads to pass properly from the bobbxns to the braid- .ing point.

All ot' he bobbins '3T of the outer set anmounted on bobbin-holdcrs .25 secured directly lo the lower carrier or table t). '.l'he thread from cach of these outer bobbins is also shown as guided and tensioned by a threzul-g'ulde and a tensicn device carried directly by said lower carrier t), these thread guides and tension devices being designated respectively b v 2S), Ztl and llt). The bobbinholdersI otl the inner set are not, however, in this construction carried directly by the table ll, but are mounted on s\vitchplatcs ,l

secured to caHier-segments movable in an annular gnideway on the lower carrier .l. and thc switch-plates are connected through suitable meansl with the carrier ll, which in this ease formed as a spider having a number of arms equal to the bobbins which it supports.

The particular construction of the switchplates. carrier segments, etc., just referred to*` dill'ers radically from anything heretofore used in braiding machines, so far as l ani aware. rl`he lower carrier t), howe'ver, may have an annular guideway somewhat similar to that heretofore used in other braiding machine This annular guideway is indicated at 31 and is formed in a ringr 3'. supported on and fastened to an annular extension 33 of the lower or main carrier t). The carrier-segments which move in.v this guideway are designated generallyl by 551'. Each. is preferably a curved member shaped lo conform to the contour of the guidewa)Y 3l in which it is to travel and having a supporlin,r face 31 to which a switch-plate may be secured. Switch-plates of suitable construction are secured to these carrier-segments and move therewith in a direction opposite to the direction of travel of the car-- rier i) and its annnlus 32, the function of these switch-plates being to control the inanner in which the threads of the outer set are interlaced with the threads of the inner set and thereby control the pattern braided by the machine. The switch-plates employed are preferably of the type or construction illustrated at. Each is a pointed segment with a wide central portion, it being so constructed as to guide one of the outer threads over either its inner or its outer face, so that the threads will pass either above or below. as the case may be, the normal line of travel of tie-e threads of the inner set. Each plate if n ferably disposed with its face substantialiy perpendicular to the line of travel of said inner threads.

An im ottant feature of this machine is that the orward end of each switch-plate is disposed above the normal path of travel of the threads of the outer set, and the switchplate normally operates to depress the threads of the outer set belowv the threads of the inner set and thus interlace the same as the two sets pass each other traveling in o ,posite directions. This normal action of e switch-plates is, however, in my machine capable of wide variation by the empl'oyment in connection with the s\ \'itcl1plates of pattern-changing devices which, taken either separately or considered collectively with the switch-plates, constitute pattern-controlling or pattern-changing means for determining; the number and sequence of the threads of one set which shall pass at one side or the other of the threads of the other set during the braiding operation` the manner in which the threads of the two sets are interlaced obviously governing the weave or pattern produced. These pattern-changing devices, together with certain other parts which will be hereinafter referred to, constitute in the construction illustrated herein the means for connecting t-he spider-armed carrier 11 with the segmental elements 34 of the upper carrier and with the switch-plates, bobbin-holders, etc., supported by said segments. f

The particular construction of the means employs-:i for controlling and varying the mode of interlaeing the threads of the. two sets may be varied wit-hin quite wide limits. That illustrated is a light, simple'and easily adjusted and operated means for the purpose, requiring no change of the parts of the machine itself but merely the adjustment or operation, or both, of parts which are a permanent part of themachine.- In this constructiont-he main element of each pattern-chan ing device is illustrated as a rotary mem er 36 supported at its opposite ends for rotation Vbetween the ends of a pair of spider-arms 37 of the carrier 11, these arms being here divided at their free ends in such a manner as to form separate supports for the ends of different rotary patternchanging members 36. Each of the rotary parts 36 isillustrated` (see Fig. 10) trunnionsdlat its opposite ends on pins 38 and as having extending lengthwise thereof spiral grooves 39 into which pass at intervals driving-pins 41 projecting up from the lower carrier 9. The guide-grooves of the rotary members 36 are here shown as four in mn ber, and the driving-pins 40 move into and ont of these grooves successively in such a manner that as'one pin is withdrawing from a spiral groove 39 another pin 40 is entering another of the grooves 39 of the same rotary member, thus assuring a positive rotation of A this rotary pattern-changing member. These members 36 have at their ends plates, such as 41, With f0ur projecting lingers, which in the rotation of the parts 36 enter and pass lthrough slots in ears fastened to the switch-plates at opposite ends thereof. The constmction is such that the rotary patternchanging'elements 315 with their end plates are always in engagement with at least one of the ears 42 with which they ooperate. and hence are always in positive driving connection with the switch-plates and the earlier-segments 34, which are thus always carried positively in their orbits by these connections from the spider-armed carrier. EachA switch-plate is also shown as having a thread-guide 43 for one of the threads of the inner set.

The manner in which the elements 36 al e rotated by the driving-pins 40 of the lower carrier as those pins move in one direction While the elements 36 are carried by the spider-arms in an orbit in the opposite direction, will be obvious from the foregoing and from the drawings illustrating these parts. The manner in which these parts 36 operate t0- control the pattern and to vary the manner in which the threads of the two sets are interlaced as they travel rapidl past each other in opposite directions will7 now be described.

Each of the rotary elements 36 carries in Y addition to the parts before described one o.'l more .thread-shifting devices constituting the pattern-changing devices proper. These thread-shifting devices may be of any suitable type and `construction so long as they are capable of performing the functions specified. In the construction illustrated each is ay light piece of wire curved to form a projection of suflcient extent for raising the louter threads as they pass under those threads. These wires are indicated -at 44, there being preferably two for each of the rotaryelemcnts 36. These thread-shifting devices are preferably spring wires and may be snapped into proper locking sockets atopposite ends of the arts 36, such as the L- haped sockets 45 (gee Fig. 10). There aire four sets of these sockets disposed about the eripherypof each rotary element 36, whicli permits tle wires 44 t0 be adjusted to different positions about the periphery of the rotary element, and also to different positions relative to each other. As each of the elements 36 is positively rotated, itwill be clear that the movements of the thread .zhifting devices 44 will at all times bear a positive relation to the movements of all of the other parts, no matter what the rotative Y positions may be to which these wires have een adjusted. The rotation of said parts affords one means for controlling the pattern made by the machine, that is to say, the wires move `in paths such that at definite periods they shift the outer threads above' their normal line of travel and above the normal line of travel of the forward ends of the switch-plates.

It will be noticed that' the high ipoint of eatt thread-shifting device 44 is adjacent to l the forward end of a switch-plate at the ,moment when one of theoater threads is to bel raised (sce Fig. 3), at which time the device 4l may operate to raise the thread so that it will pass along the upper edge of the next switch-plate instead of following its normal path under the lower edgf of said switch-plate.

It will be obvious that by properly regulatini:r the number and positions ot' the thread-shifting devices carried by each rotary element 36 and by positively rotating the parts 36 in the manner illustrated and described, many variations. in the normal operation of passing each outer thread under each switch-plate may be obtained. Thus. b v properly adjusting or setting the dill'erent sprung wires -t-l to proper circmnferential positions about their respective rotary elements 36, the outer threads may be caused to pass above every other switch-plate or above two or more switch-plates successively, as desired, and various other moditications of the mode of interlaciug the two sets of threads are possible by the employment of the devices illus? :ated or of suitable. moditications within the scope 0f my invention, without removingr from the machine any part thereof and without adding any weight thereto. It will be' seen, too, that all of these parts of the pattern-changing apparatus which permit the weaving of various kinds of braids are light and easy running elements and Vdo not reduce the speed of operation of the machine.

ln Fig. t) I have illustrated at 46 a removable section of the ring 32 in which is formed the guideway for the carrier-segments. lhis removable section is long enough to permit the carrier-segments 3l with their `attached switch-plates, bobbinholders, etc., to be dropped into the guideway 31 through the ,opening presented .at said point at the top of the ring 32 and then shifted to their proper orbital positions. When all of the carrier-segments are in place the section -t6 of the ring may be fastened iu position as illustrated in full lines in Fig. 9, to close the openinv.- Various features of the machine require no extended description. `For example, any suitable means may be employed for controlling the movements of the threads of the inner set including the tension thereof. In addition to the thread-guides 43, shown in connection with these threads, spring-catches or detents are illustrated at, 47 for holding the bobbins of thelinner set in place on their switch-plates.
